test(interest): 补充场景1固定/浮动+场景2+单笔GLMS利息回归测试

Browse Source 
- SwapInterestScenario1And2Test: 场景1浮动(8,利息=0) + 场景1固定(12) + 场景2第一重置期内平仓(12)，共32例
- SwapSingleTradeVerificationTest: 单笔GLMS-0007/0006 第三重置期/到期平仓 + 30%+70%守恒，共4例
- 全部走真实生产函数(GetInterests / SaveAutoEodWithCloseInterestPosition)，对照 Excel oracle(AO/BL/BN/累计利息)
- 与场景3/4 合计 60 例全绿(容差0.01)，非 re-baseline
